The meteoric waters , which represent a renewable source and require simple and inexpensive treatments for their re-use, have been collected in a special deposit, located above ground, thus allowing not to realize the excavation works necessary for its installation. The entire recovery cycle is reused for consumption for cleaning and watering the gardens. All systems are of new generation and with the use of photovoltaics and bioclimatic devices, the building is in energy class A4 .
